I saw a picture on Reddit of a Chronomaster Sport with an Omega rubber strap. I assume the strap is from a Seamaster. Does anyone know what model Seamaster it might be?

 

Awesome look on the Zentih to be sure. The strap looks like it could be from a Seamaster 300... here is a link with similar looking straps.
